A very scholarly work (common names are never mentioned at all). This is the bible for entomologists who work with damselflies. Some color plates and many highly detailed and magnified illustrations. Geographic coverage includes Canada, the United States, the northernmost Mexican states, and the Greater Antilles.

A lovely little book, just under 100 pages. Covers all 69 species/forms of damselflies from the northeastern US (Virginia northward) and eastern Canada. It should be useful for all of the eastern US. Each species account is a full page and includes: life history, range map, flight dates, identification tips, detailed illustrations of both sexes, and smaller diagrams showing anatomic details. There is an introduction to damseflies with detailed diagrams explaining anatomic terms, and there are two pages of references. The book has superior typography and design.

Stunning close-up videos of common dragonflies and damselflies. Video showing behavior and a variety of angles is a great supplement to a field guide. 50 widespread eastern species are covered in a one-hour DVD. Sequences show life cycle and habitats, so it is more than a field guide.

Coverage of North Carolina species is particularly good, since one of the authors is based there. The footage of damselflies is especially welcome, since there is no in-print field guide for the eastern US.

My only wish is for a booklet to accompany it, and subtitles. (There are explanatory notes included in the DVD.) My copy had one minor glitch that only showed up on one DVD player, but not on another. This was not a fatal flaw, only annoying. (I have seen similar problems on other commercial DVD's.)

This practical guide provides a vast wealth of knowledge for the Francophone naturalist. It allows the identification and study of dragonfly naiads, either as underwater nymphs, or as exuviae left by new adults. The proposed identification key, creative and generously illustrated, allows to differentiate with confidence the 52 Zygoptera and Anisoptera genera found in Quebec and adjacent regions.
